APPARATUS FOR TREATING HIDES PREPARATORY TO TANNING.

Specification of Letters Patent.

Patented Oct. 17, 1905.

Application filed April 27,1905. Serial No. 257,742.

'To all whom, it may concern.-

Be it known that I, JAMES WILLIAM DECK- ERT, a citizen of the UnitedStates, residing at Oakville, in the Province of Ontario and Dominion ofCanada, have invented certain new and useful Improvements in Apparatusfor Treating Hides Preparatory to Tanning; and I do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same. reference being had to the accompanyingdrawings,and to the letters of reference marked thereon, which form apart of this specification.

This invention relates to new and useful improvements in apparatus fortreating hides, and especially in the provision of mechanism forsoaking, liming, baiting, and tawing hides and skins; and it consists inthe provision of a partition-tank in which the hides are sus--.

pended and in which a circulation of the treating liquid is produced bythe rotary movement of a winged wheel positioned in a passage-wayunderneath the partition and causing the liquid to circulate over thetop of the partition from one compartment into the other.

The invention consists, further, in connection with the foregoing, ofmeans for hoisting the solids which are precipitated from the liquid andin the returning of the liquid to the tank containing the hides.

The invention is illustrated in the accompanying drawings, which, withthe letters of reference marked thereon, form a part of thisapplication, and in which drawings Figure 1 is a sectional view throughmy improved apparatus. Fig. 2 is an enlarged sectional view showingparts of the invention in elevation, and Fig. 3 is a sectional view online 3 3 of Fig. 1.

Reference now being had to the details of the drawings by letter, Adesignates a tank which is provided with an exit-opening controlled bythe plug A, and said tank has a central partition B with a spaceintervening between the bottomthereof and the bottom of the tank,through which space the liquid contained within the tank is adapted tocirculate. The upper end of said partition is below the top of saidtank, aflording a space over the top whereby liquid may flow from oneside of the partition to the other. Hooks C are fastened to the flangeD,'mounted upon the upper end of the partition B, and also to the hooksD, which are fastened to the projections D on the ends of the tank.

F designates a shaft which is journaled in suitable bearings and haskeyed thereto a winged wheel G, the wings of which are adapted to turnin the space below the partition for the purpose of causing a current ofthe liquid in the tank. A sprocket-wheel G is also fixed to the shaft F,and a sprocketchain H, passing over the wheel G, also passes about asprocket-wheel G fixed to a shaft G mounted in the hangers G", which maybe suspended from the ceiling of a room. A clutch-wheel I (shown clearlyin Fig. 3 of the drawings) is splined to the shaft G and has a lever I,which is pivotally mounted at 1 Fig. 1, and engages said clutch I forthe purpose of throwing the same longitudinally upon the shaft G inorder that the lugs I may engage the holes J in the hub of the pulley J,which is loosely journaled upon the shaft G Motion is imparted to theshaft G through the pulley N, which is keyed to said shaft and to whichpulley belted connection I is had with the pulley N upon the shaft N andsaid shaft N is driven by gear connection with a motor 0.

M designates a conduit which empties into the reservoir M and is adaptedto convey the liquids which make exit from the tank A into the reservoirM. Mounted in the hanger Q is a shaft Q, and Q designates a pulley whichis keyed to the shaft Q and has belted connection Q with a pump Q. Thecasing of said pump has a pipe P leading therefrom downinto thereservoir M, the lower end of said pipe being perforated, and anexit-pipe P leads from the pump Q} and empties into the tank L, which issimilar in construction to the tank A on a smaller scale and is providedwith a partition L and a winged wheel L mounted underneath the partitionthereof, and said wheel is driven by sprocket-chain connection L with asprocket-wheel L*, rotating with the shaft S, which also carries apulley S, which has a belt S connecting the same with a pulley Q uponthe shaft Q.

Mounted in suitable hangers T is a shaft T, having a gear-wheel T on oneend thereof and in mesh with a bevel-gear T upon the shaft S. A sprocketT is mounted upon the shaft T, and a sprocket-chain T connects the samewith a .sprocket wheel T, which is mounted upon a stub-axle T mounted insuitable bearings. One end T of said stub-axle is forked and has pivotalconnection with the stem W of the spiral hoisting-worm W, which ismounted in suitable hearings in the inclined passage-way. (Shown clearlyin Fig. 1 of the drawings.) The lower end of said hoisting-worm-extendsthrough the bottom of the tank Maud is adapted to raise the solidparticles which may be precipitated from the liquids and deposit thesame at the upper exit end of said worm. An exit-pipe Y leads from thetank L to the tank A, and a plug-valve L is provided to fit the entranceto said exitpipe, and valve-regulated pipes X and X lead into the tank Land by which'liuids may be introduced into the tank L.

It will be observed that secured to the lower portion of the partition,which divides the tank into two compartments, are the curved members Ghaving flanged edges underneath which the winged wheel rotates. Saidmember is provided for the purpose of causing the paddles as they turnto be out of the current of the liquid and, further, to prevent backpressure upon the upper portion of thewheel.

From the foregoing it will be observed that by the provision of anapparatus embodying the features of my invention the hides may bethoroughly treated by the violent agitation of the liquids, which arecaused to circulate from one compartment to the other of the tank A, andafter drawing off the liquids from the bottom of the tank theprecipitated particles are hoisted by the hoistingworm, and the liquidmay return to the tank L, where after being thoroughly agitated by themotor-wheel working therein it may be fed back into the tank A.

While I have shown a particular form of apparatus illustrating myinvention, it will be .understood that I may vary the details ofthesame, if desired, in various ways without in any way departing from thespirit of the invention.

Having thus fully described my invention, what 1 claim as new, anddesire to secure by Letters Patent, is

1. An apparatus for treating hides comprising a compartment-tank with aspace intervening between the partition thereof and the bottom of thetank, the upper end of the partition being below the top of the tank, awinged wheel mounted in suitable bearings underneath said partition,means for driving said wheel whereby a current may be formed with theliquid in the tank, a reservoir with a valve-regulated passage-wayleading from said tank thereto, means for returning the liquid from saidreservoir to the tank, a wormshaft mounted in suitable bearings with itslower end extending into said reservoir, and means for operating saidshaft, as set forth.

2. An apparatus for treating hides comprising a compartment-tank with aspace intervening between the partition thereof and the bottom of thetank, the upper end of the partition being below the top of the tank, awinged wheel mounted in suitable bearings underneath said partition,means for driving said wheel whereby a current may be formed with theliquid in the tank, a reservoir with a valve-regulated passage-Wayleading from said tank thereto, a pump, a second partitiontank intowhich the liquid is raised from the reservoir by said pump, a worm-shaftmounted in suitable bearings and extending into the bottom of saidreservoir designed to elevate the precipitated matters from said liquid,and means for agitating the liquid in said second tank, as set forth.

In testimony whereof I hereunto affix my signature in presence of twowitnesses.

JAMES WILLIAM DEOKERT.
